Stockholm

For some travelers the opportunity to take a guided walking tour of historic buildings is about as appealing as taking a walk through an airport security checkpoint. Yet even those travelers would find the offerings by Stockholm tour operator Upplev Mer cool. That’s because their tours don’t walk alongside acclaimed architecture—they walk on top of it!

Literally. Participants on a Upplev Mer tour scamper across Stockholm’s roof tops like Mary Poppins. Except, instead of using an umbrella for safety, they rely on hard hats, harnesses and cables.

Anyone can (attempt to) sing Dancing Queen in a karaoke bar. But what about singing Dancing Queen along with a holographic rendering of ABBA and then fielding a real live phone call from one of the original band members? That’s possible only if you are exceedingly wealthy, eccentric and well-connected — or if you visit The ABBA Museum. It’s part of a new complex in Stockholm that celebrates Sweden’s second most famous export after Ikea furniture: The Swedish Music Hall of Fame.

Next time you fly out of Stockholm’s Arlanda International Airport, spend the night on an airplane before boarding your airplane. On the airport grounds there’s an old Boeing 747 has been converted in a hotel, the Jumbo Hostel.
